Please correct me if I am wrong at any point. I looked around online and from what I've read, if you lift the red, black, and white wires from the system board you will need to buy a new system board. Yet, in the process of replacing the battery, you need to separate the wires anyway and solder the wires from a new battery. What I don't understand is, why is a new system board necessary if you accidentally lift the wires? Is it possible to remove the residue and the broken tips of the wires from the soundboard and replace it with a new battery? The reason for asking is my black and white wires accidentally separated from the soundboard as I was repairing my screen, and I'm wondering if this is still repairable without having to buy a new system board. Like I said, feel free to correct me if I am wrong about anything. Thanks!
